RINNESHA
Making people-friendly goods, with everyday life in mind.
Based in Tsushima, Aichi, RINNESHA develops and sells additive-free foods, organic farm products, and everyday natural goods. Founded in 1977, the company runs a retail business for both its own PB items and selected NB products, with stores and an online shop. Signature items include Kikka Senko (a natural insect-repellent incense made without synthetic pyrethroids or added coloring), a Kikka insect spray using natural pyrethrum extract and Hokkaido mint-derived menthol, camphorwood incense made without common additives, and Aka-maru mint products from its own farm in Takikami, Hokkaido.
Why We Love It
If you are new to the brand, start with Kikka Senko and choose between the standard (about 6 hours) and the square mini (about 3 hours) depending on where and when you burn it. For quick spot care, pair it with the Kikka insect spray. On days you want a softer fragrance, camphorwood incense brings a gentle, natural aroma. And for a clean, refreshing note, try Aka-maru mint — either as an essential oil or as a simple mint herbal tea.
PROFILE About the Company / Workshop
RINNESHA was established in 1977. Its head office and Tatsukomi store are in Tsushima, Aichi, alongside a Uji location that also serves as a distribution center. The company also lists a Tokyo office. Beyond Aichi, it operates the herbal research facility Honso Kenkyujo RINNE inside VISON in Taki, Mie, and maintains a branch and farm in Takikami, Hokkaido — bases that support both product making and storefront proposals.
Among the best-known items is Kikka Senko. It is introduced as a natural insect-repellent incense that does not use chemical components, including synthetic pyrethroid insecticides, and uses no added coloring. The standard set contains 30 coils and burns for about 6 hours per coil, and is labeled as domestically produced. Variations such as a square mini type (about 3 hours per coil), longer-burning versions, and thicker-smoke options are also offered.
The Kikka insect spray extends the same idea in a different form. It uses natural pyrethrum extract and menthol from Hokkaido mint, and comes in a 180 ml trigger bottle, with use described for controlling nuisance insects such as midges, drain flies, and mites. For a different scent profile, camphorwood incense is made with camphorwood oil and honey and is described as being produced without typical additives; it is listed as 70 g and marked as domestic.
From its Hokkaido farm, the company produces Japanese mint and offers Aka-maru mint products. Aka-maru mint oil is steam-distilled from mint cultivated without pesticides or chemical fertilizers; the origin is shown as Hokkaido and the bottle size is 10 cc, with a usage leaflet included. The same mint is also sold as an herbal tea with mint as the sole listed ingredient. RINNESHA's business description also lists PB/NB retail, wholesale items, quasi-drug products such as MONE and Fabre ex, and school programs including English conversation and tai chi.
